Heat will keep arriving earlier. It will keep lingering longer. It will keep settling hardest in the same neighborhoods unless something changes.
The strategy is not mysterious. Cities know what to do. The country knows what to do too.
Success will not look like a graph bending gently downward.
It will look like a bedroom that finally cools after midnight.
